For all of my fellow bibliophiles throughout the world, I offer you the El Ateneo Grand Splendid in Buenos Aires, Argentina.
Built as a tango theatre in 1919, at the height of the South American craze for that sensual dance, the Teatro Grand Splendid was transformed to become a cinema only ten years later. It had the distinction of being the first cinema in Buenos Aires to show sound films. Under threat of demolition due to a poor economy in 2000, it was transmogrified into its current existence by the Grupo Ilhsa, which owns 40 bookshops.
Today, more than a million visitors from all over the world ogle at its opulence and buy a few books. Check out the website below for more stunning photos.
